These are the readings that are made during the actual experiment, both of the weight movements and of the corresponding pendulum swings or inclinometer values. Obviously you must be careful not to include any clearly spurious readings as Calc will use all of the entered data in its calculations.
Two methods of analysis are available are available
-
The standard method takes the total moment & total inclination angle for each weight shift and calculates the individual GMs as follows

where

The total GM is then taken as the average of the individual values
-
Alternatively, linear regression can be performed on the data (tan(f) vs. moment), a straight line fitted to the data and the slope of the line found. The total GM is then calculated as follows:
